Zusammenfassung:Selected artifacts, which may be based on distortions or selected attenuation features, may be reduced or removed from a reconstructed image. Various artifacts may occur due to the presence of a metalobject in a field of view. The metal object may be identified and removed from a data that is used to generate a reconstruction. 能够减少重建图像中或从中去除可能基于失真或所选衰减特征的所选伪像。可能由于金属物体存在于视场中而出现各种伪像。能够标识所述金属物体并将其从用于生成重建的数据中去除。
